From ee166a0e71947e0ebeb044fd2277435f665270ac Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Tue, 3 Mar 2009 19:23:36 +0200 Subject: ath9k: Check virtual wiphy state on tx() mac80211 should not be requesting us to transmit frames on paused wiphys since we stop the TX queues. Just in case, add debug code to make sure we catch if this were to happen. Signed-off-by: Jouni Malinen Signed-off-by: John W.
